One of the first things that should stick out is that we’re using themock.patchmethod decorator to mock an object located atmymodule.os, and injecting that mock into our test case method. Wouldn’t it make more sense to just mockositself, rather than the reference to it atmymodule.os...
Before diving into theside_effectparameter, let’s briefly review the basics of mocking in Python. Theunittest.mockmoduleprovides theMockclass, which allows us to create a mock object with specified behaviors for function or method calls
